Activating c-KIT mutations confers oncogenic cooperativity and rescue RUNX1-ETO induced DNA-damage in human cells


ABSTRACT: REtr causes genomic instability in U937 cells. Activated forms of c-KIT, like c-KIT(N822K), rescues the Retr induced genomic instability by increasing the rate of DNA repair by homologous recombination Human U937 cells were transduced with retroviral vectors encoding REtr or c-KIT(N822K), expanded in culture and FACS selected prior to molecular analysis

The RUNX1/ETO (RE) fusion protein, which originates from the t(8;21) chromosomal rearrangement, is one of the most frequent translocation products found in de novo acute myeloid leukemia (AML). In RE leukemias, activated forms of the c-KIT tyrosine kinase receptor are frequently found, thereby suggesting oncogenic cooperativity between these oncoproteins in the development and maintenance of t(8;21) malignancies. In this report, we show that activated c-KIT cooperates with a C-terminal truncated  ...[more]
